There must have been two Alois Huelskamps. The oldest Alois was born in 1858 and died in 1891. He was born prior to his Father Frank was married. Perhaps Frank's wife had Alois prior to her marriage and Frank may not have been the Father of the oldest Alois. The second Alois supposedly was born on 1871 so it is doubtful he is the oldest Alois' son and the other info says he is a son of Frank and Theresa H.
